This is confusing because the brake line clamp screws are a machined thread with a thread cutting flute.Gas tank strap screws are a sheetmetal tapping thread with a point. The two are quite different.

Brake line screw 3958062 / B-10412 http://www.amkproducts.com/bulk3.asp?part=B%2D10415This is the kind of screw I expected to see used here but, without the hex-flange because a separate washer is used. No where on these cars have I seen a hex-flange with a washer. Only hex with washer or hex-washer.

Steve & Mark X22, I finally found the missing Air shield screw I was looking for. I thru it in with my front end sheet metal bolts. Any way I am sure this is it because when I took it out I remembered it was ground on one side like it hit the pavement or something. I am now questioning if the other holes I measured as .250" were filled in slightly from powder coating. I hate to put a 5/16" tap into it and open it up more but I have to find out what size bolt goes in there.I will let you know.George

Has the correct size screw configuration been determined?There is something wrong with the 69 AIM C60 B4 UPC.From an assembly standpoint I can not imagine a line worker having to stack 9 washers on screws and installing them while holding up the shield. It would be more efficient to have a washer and screw asm.The screw hole piercings of .277/.281 would only work for a self tapping 5/16-24 or 32 if I am correct.The only screw I think would work using the bolt and washer assumption is an over sized self tapping screw ( hex head wo/ washer) used on the front sway bar. Rick's shows them as SS-415 and are used when the screw holes are stripped. Bob

I was going threw some boxes today and came across the bag with my original AC shield bolts, cleaned them up & they are the same as my fuel line clip bolts #3958062.These are the ones I took out because I bagged them. Wish I did that with all the bolts. Also they thread into the holes good not loose.George
